European Probiotic Association awards Peter de Schryver
Press release
The European Probiotic Association (EPA) awarded the Jules Tournut Probiotics Prize 2012 to Peter de Schryver, from Ghent University, for his innovative research project on the use of microbial products and microorganisms in animal nutrition.
The awarding was held on November 13, 2012, at EUROTIER tradeshow. Altogether, the quality and diversity of research projects submitted demonstrate that probiotics benefits go beyond zoo technical performance and pave the way for innovative applications in the field of immunity, but also stress management or even reproduction.
The aim of the EPA Jules Tournut Prize is to support research and innovation in the field of probiotics for animal nutrition. The studies submitted covered a range of target species and benefits, sign of the broad potential of probiotics for sustainable animal production.
Peter de Schryver's project aimed at improving performance and welfare in aquaculture thanks to an original approach: the use of poly-β- hydroxybutyrate (PHB), which he describes as a microbial energy storage polymer, an important source of energy for bacteria. PHB thus appears to play a prebiotic role in aquatic species, resulting in improved performance and resistance to pathogens.
By combining this compound to a probiotic bacteria (synbiotic approach), the young researcher showed that both agents had a synergistic effect to protect fish against pathogens. Nevertheless, when asked if this new approach could be applied to various species Peter de Schryver reckons that, "it could certainly work in land farmed animals that have an even more developed digestive system". The use of PHB in synbiotic approach for animal nutrition thus appears as a promising field.
Moreover, the young researcher is convinced that, especially in aquaculture, the digestive microbiota is often underestimated. Another interesting aspect of his study is that he looked into the Artemia microbiota richness and diversity and found that PHB had a positive effect on the microbiota diversity and evenness, an asset for microflora stability and protection against pathogens.
Altogether, these very original studies, and the totality of studies submitted to the EPA show that the field of possibilities for probiotic applications is far from limited, introducing some new potential areas of applications such as reproduction, immunity or even stress, to the list of more established benefits, namely performance, gut microflora stabilisation, protection against pathogens.
